Toshiba's new Slim SelectBay technology provides maximum adaptability for different tasks. Depending on the application, you can quickly add a second hard disk, or swap a CD-ROM for a DVD-ROM or a CD-RW/DVD-ROM drive.

Other options include a CD-RW drive and secondary battery pack. For cost-efficient compatibility the Slim SelectBay is common to both the Toshiba Tecra 9000 and the ultra-portable Portégé 4000 series.
